This Privacy Policy explains how Heat Pump Cost Calculator (heatpumpcostcalc.co.uk) collects, uses, stores, and protects personal information when you use our website and heat pump cost calculator tools.
1. Who we are
Heat Pump Cost Calculator operates heatpumpcostcalc.co.uk, a free online resource that helps UK homeowners estimate air source heat pump installation costs and Boiler Upgrade Scheme grant deductions, and optionally request quotes from MCS-certified installers. We are the data controller for personal information processed through this website, except where third-party services (such as installer quote partners) act as separate controllers.

2. Information we collect
We may collect the following categories of information depending on how you use the site:
- Calculator inputs: current heating fuel (gas, oil, LPG, or electric), property size by bedroom count, and UK postcode.
- Contact details: name, email address, telephone number, and message content if you contact us directly.
- Quote form data: if you complete an installer quote form embedded via our partner Leads.work, you may provide additional contact and project details directly to that service.
- Technical data: IP address, browser type, device identifiers, referring URLs, pages viewed, and approximate location derived from IP or postcode.
- Cookie data: see our Cookie Policy for details on cookies and similar technologies.
3. How we use your information
- Provide heat pump cost estimates, grant calculations, and personalised results.
- Store lead records locally when enabled, to support follow-up and service improvement.
- Improve calculator accuracy, fix errors, and analyse aggregated usage trends.
- Respond to support requests, data subject enquiries, and correspondence.
- Facilitate connections with MCS-certified heat pump installers when you choose to request quotes.
- Maintain site security, prevent abuse, and comply with legal obligations.
4. Legal bases for processing (UK GDPR)
We rely on one or more of the following legal bases:
- Consent: where you opt in to marketing, cookies (non-essential), or submit a quote request.
- Legitimate interests: operating and improving our calculators, securing the website, and understanding aggregated demand — balanced against your rights.
- Contract: where processing is necessary to deliver a service you request.
- Legal obligation: where we must retain or disclose information to comply with applicable law.
5. Third-party services
Heat Pump Cost Calculator may integrate third-party tools including hosting providers, analytics (if enabled), and Leads.work quote forms. When you interact with an embedded quote form, your data may be processed by that provider under their own privacy policy. We do not sell your personal information.
6. Data sharing
We may share information with:
- Hosting and infrastructure providers that store and deliver the website.
- Installer quote partners when you explicitly submit a quote request.
- Professional advisers or authorities where required by law.
7. International transfers
Some service providers may process data outside the UK. Where this occurs, we aim to use appropriate safeguards such as UK International Data Transfer Agreements or adequacy regulations.
8. Data retention
We retain personal data only as long as necessary for the purposes described above, including:
- Calculator session and lead records: typically up to 24 months unless a longer period is required for disputes or legal compliance.
- Support emails: up to 3 years from last contact.
- Server logs: usually 30–90 days.
9. Your rights
Under UK data protection law you may have the right to:
- Access a copy of your personal data.
- Rectify inaccurate information.
- Erase data in certain circumstances.
- Restrict or object to processing.
- Data portability where applicable.
- Withdraw consent at any time (without affecting prior lawful processing).
- Lodge a complaint with the Information Commissioner’s Office (ICO) at ico.org.uk.
To exercise your rights, email with sufficient detail for us to verify your request.
10. Security
We implement appropriate technical and organisational measures to protect personal data. No online transmission is completely secure; please use strong passwords and avoid sharing sensitive information unnecessarily.
11. Children
Our services are intended for adults making household energy decisions. We do not knowingly collect personal data from children under 16.
12. Changes to this policy
We may update this Privacy Policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the site after changes constitutes acceptance of the revised policy.
